); virtual;
Parameters
Parameters 
Description 
AUserName 
Mail list or alias to be expanded.
 
AResults 
Membership in the list or alias. 
Description

Expand is a procedure used to determine if the argument in AUsername is a valid mailing list or mailbox alias on the server, and retrieves the email addresses for the membership of that list in AResults. 

Expand uses the SMTP EXPN command to retrieve the results, with one name and email address per line. 

The following is an example of successful result values that might be returned in AResults when using Expand with the Username 'Example-People': 

 

  // var
  //  IdSMTP1: TIdSMTP;
  //  AResults: TIdStringList;
  IdSMTP1.Expand('Example-People', AResults);
